The Rigol DSA832E is a 3.2 GHz spectrum analyzer engineered for RF signal characterization and measurement across demanding applications. Built on all-digital IF technology, it delivers enhanced reliability and measurement fidelity. The instrument combines high sensitivity—down to -161 dBm typical with preamplifier enabled—with 1 Hz frequency resolution and broad span capabilities from 100 Hz to 3.2 GHz, making it suitable for component testing, interference analysis, and wideband signal assessment.
